Filed: 1987-01-12
Abstract: PURPOSE:To detect a trouble at an early stage and to minimize the hindrance of productivity, by detecting the coil density of a metal wire formed to a spiral shape during conveyance and directly detecting the abnormality of the conveyance condition of the metal wire in accordance with the detection signal thereof. CONSTITUTION:The conveyor 2 imposed with the spirally formed metal wire 1 is driven by a motor 4 via a roll 3 to covey the metal wire 1 continuously. The detection signal of a coil density detector 5 installed in the upper or lower part of the conveyor 2 along the center line of the conveyor 2 is inputted via a signal line 6 to a comparator 7. An upper limit value HL and lower limit value LL are previously set in the comparator 7 and the output signal thereof is connected to an alarm controller 8. The detection signal exceeds the upper or lower limit set value when the metal wire 1 touches the device, etc.; therefore, an alarm is emitted by the controller 8 and is announced to an operator. A stop signal is simultaneously outputted to a motor 4 to stop the conveyor 2.

Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a protecting method for a centrifugal compressor, for protecting the centrifugal compressor from surge. SOLUTION: The change rate of discharge pressure of a second compressor 5, to be detected by a pressure detector 9 per unit time in the constant time is calculated by a computer part 10a, the change rate and a reference value as an upper limit allowable value of the pressure change rate in which surge is generated are compared with each other in a judging unit part 10b with an absolute value. When the change rate larger than the reference value to be counted in the constant time becomes the specified revolutions or more, that surge is to be generated is judged, and an unload valve 8 is unloaded by a control unit 10c.  When the change rate larger than the reference value to be counted in the constant time after unloading is the specified revolutions or more, it is judged that the unload valve 8 fails and is not unloaded, the operation of the first and second compressors is stopped by the control unit 10c, and therefore, a centrifugal compressor is protected from surge even if the unload valve 8 fails.
